The study of change management intends to identify what can be active in an organization, making it evolve in a direction that follows or resists to the goals defined by those in charge. This study wants to compare the propositions put forward by a ventriloqual approach to communication, as defined by François Cooren in Action and agency in dialogue (2010), with two works dealing with organizational change : The knowledge-creating company (Nonaka & Takeuchi, 1995) and The Dance of Change (Senge, 1999). The goal is to understand how this ventriloqual perspective allows a better understanding of the nature and contributions of these different forms of agency. Through this comparative inquiry, the ambition of this work is also to offer a perspective on ventriloquism itself, by highlighting its most innovative aspects, in order to demonstrate the progress constituted in particular by nonhuman agency and the dislocality of interaction.
